Well hell Mark!
I agree with much of what you said up til this paragraph. That's just flat wrong! The improvement in ICE power and economy over the past decades, but especially in the past few years, accomplished while reducing emissions to a non-issue, has been a moon-shot accomplishment.
Meanwhile, 68% of the juice to charge your Rivian will be electricity generated by a coal burning powerplant or natural gas, which are only 30% efficient.Newold1 wrote: ↑Sun Feb 17, 2019 11:13 pm When we consider today's best average consumer used ICE automotive engine with all the latest advances still operates at about 35 percent overall efficiency you can start to understand my thought that the door was left open to long by the industry and future of the ICE's fate was written in the stone.
An automotive engine might have a peak thermal efficiency in the 35% range (Prius engine with Atkinson cycle slightly exceeds this) but in most applications, automotive engines spend a lot of their time operating "off-design" - at combinations of speed and load which have considerably lower efficiency; when it's idling that efficiency is 0%. The average thermal efficiency, tank to wheels, for a normal non-hybrid vehicle, is quite a bit lower than this.Newold1 wrote: ↑Sun Feb 17, 2019 11:13 pm When we consider today's best average consumer used ICE automotive engine with all the latest advances still operates at about 35 percent overall efficiency you can start to understand my thought that the door was left open to long by the industry and future of the ICE's fate was written in the stone.
But alas, no one told Trump...
There are always outliers, but the facts are still the facts; 99% of daily use trips in the US are within EV range.
Agree again. With two paid-for ICEs in the garage, an EV would never pay for itself in fuel savings, but the Bolt is just a better ride and a better vehicle for my wife's many short trips in cold weather.
The TM3 is a better car in many ways, but the Bolt is a better buy in most every way.MikeB wrote: ↑Wed Feb 27, 2019 11:29 amAll that said, I wouldn't mind having a Chevy Bolt for running around town. With an actual grille, it sure looks cooler than a Model 3, and actually has a a "dashboard" in the proper location! But, hey, I wouldn't be able to snick my nose in the air and say that I own a Tesla.
